According to the National Institutes of Health, about 50% of the population over 50 will get hemorrhoids. Hemorrhoids occur when the veins around the anus or the lower rectum become swelled and inflamed due to excessive pressure in the abdomen. If you suffer from hemorrhoids, it can be an indication for changes to your diet and lifestyle, such as exercising more and eating more fiber-rich foods.

There are two kinds of hemorrhoids: internal, which usually cause minor discomfort, and external, which are closer to the anus. External hemorrhoids can flare up suddenly and painfully. If you notice blood on your toilet paper or in your stool, these can be symptoms of hemorrhoids or a more serious condition, and you should consult your doctor.

While pregnancy, aging and other factors can contribute to hemorrhoids, the main cause is excessive straining during bowel movements due to frequent constipation.  To prevent and relieve hemorrhoids, the Harvard School of Medicine recommends increasing the fiber you eat, getting 20-30 minutes a day of moderate exercise and drinking adequate fluids.

Dietary fiber prevents and eases hemorrhoids by softening the stool and making it easier to pass. For people who suffer from hemorrhoids, a softer stool causes less irritation to the inflamed tissues. For everyone, less time spent sitting on the toilet means less pressure and less straining.
